To all whom it may concern:

Be it known that I, FRANK W. FLAVIN, a citizen of the United States, and a resident of Naples, in the county of Clark and State of South Dakota, have made certain new and useful Improvements in Oilers, of which the following is a specification.

My invention is an improvement in oilers, for use with crank or wrist boxes, or in any other position where itis desired to feed lubricant by force to a bearing or the like, wherein a container is provided for connection with the bearing or other part to be oiled, and other mechanism operated by the moving of the rotating element for feeding the lubricant.

In the drawings: Figure l is a top plan view of the improved oiler, Fig. 2 is a front View, Fig. 3 is a longitudinal section, Fig. 1 is a side view at right angles to Fig. 2, and Fig. 5 is a side view showing the oiler in use.

The present embodiment of the invention comprises a cylindrical container, con sisting of the cylindrical barrel or body 1, having one end closed by a head 2, provided with a central longitudinally extending nipple 3, the said nipple having an external polygonal portion a adjacent to the head for engagement by a wrench or other tool, and a threaded portion 5 at the end remote from the head, for engaging a threaded opening to secure the container in place.

The head 2 is provided with an annular flange 6, which its around the lower end of the body or barrel 1, and the said head is provided with diametrically opposite perforated lugs 7, through which. are passe angle, bolts, for connecting the head to the body or barrel. Each of the angle bolts comprises a body 8 having one end threaded, and having at the other end an angular portion The portions 8 are passed through the lugs 7, and are engaged by nuts 9 at the opposite side of the head from the body.

The lugs or portions 8 of the angle bolts are adapted to engage over a marginal rib 10 at the adjacent end of the body, and when the nuts are turned in the proper direction it will be obvious that the head will be clamped against the adjacent end of the barrel. The opposite end of the barrel or body is closed by a. head 11 which fits within the body, as shown in Fig. 3.

A. plunger or piston is arranged within the body or barrel of the container, said plunger being composed of three superposed disks 12, 12 and 12*, together by screw bolts and nuts 13. The disks 12 and 12 have each a central opening 14, and the disk 12 is provided with a central opening 15 which is internally threaded, and which 14, but the opening 1.5 is of less diameter than the opening 1 1. The disk 12 is of such diameter that it will it within the body or barrel 1 smoothly, while the disks 12 and 2 are of slightly less diameter, as shown in A plunger rod 16 is connected with the plunger, the said rod having a threaded portion 16 for engaging the threaded opening 15 of the disk 12". The upper end of the rod is reduced, as shown at 17, and the extremity of the reduced portion is polygonal in cross section, as shown at 17 A crank 18 engages with the polygonal portion, the crank having a socket 18 fitting the said portion; and the polygonal portion, as well as the greater portion of the reduced portion is outside of the head 11.

It will be obvious that when the plunger rod 16 is rotated, the plunger will be moved toward and from the head 2. A worm wheel 19 is journaled on the reduced portion 17 of the plunger rod, between the socket 18 and the head 11, and the said wheel is engaged by a worm 20, on a worm shaft 21, which is journaled in bearing arms 22, mounted to swing on a bolt 23, which is journaled in a bearing lug 24: extending radially from the head 11.

The arms 22 are mounted to swing on the pivot bolt 23, to permit the worm shaft to be swung towardor away from the worm wheel, and by means of the bolt 23, the arms may be rigidly secured to the lug 2 1, to hold the worm in close engagement with the worm wheel. The worm wheel is provided with a radial arm 25, and a wheel 26 is journaled in the arm. A pendulum arm 27 is keyed to the outer end of the worm shaft 22, and the arm is provided with a weight or pendulum. 28 at the end remote from the worm shaft.

The head 11 is provided with an extension 29 lying diametrically of the container, and the said extension is provided with a transverse chamber or recess 30, in which is arranged a ratchet wheel 31, which is keyed to the plunger rod 16. A pawl 32 engages the teeth 0" the ratchet wheel, and the pawl is carried by a pawl arm 33, which and the disks are secured registers with the openings l if a is pivoted intermediate its ends to the end at" the extension 29 remote from the worm shaft 21 as indicated at 34. A coil spring 35 has to the extension, and the spring normally. acts to hold the pawl in engagement with the teeth of the ratchet wheel.

The pawl arm extends on the opposite side of the extension, from the pawl, and the end of the said arm is bent upward, asindicated at 33, and a cam plate 36 is secured to the portion 33 of the arm. The cam plate is in position to be engaged by the roller 26 on the radial arm 25, and when the cam plate is engaged by the roller, the plate will be moved outward, to swing the pawl arm, to cause the pawl to advance the ratchet wheel 31, to move the plunger shaft in a direction to force the plunger downward. It will be obvious that for every complete rotation of the worm wheel, the pawl arm will be swung to advance the ratchet wheel.

The improved oiler when in use is arranged as shown in Fig. 5. The threaded portion of the nipple 3 is engaged with an 7 opening in the bearing 37 for the wrist pin 38. The container is filled with lubricant by first releasing the pawl from the ratchet wheel and turning the crank in the reverse direction, until the plunger is at the head 11. The nuts 9 are then loosened to permit the angle bolts 8 to be turned to release the rib 10. The container or barrel is then filled, after which the head 2 is replaced. The angle bolts are turned to engage the portions 8 with the rib, and the nuts are tightened.

- When the device is arranged as shown in Fig. 5, and the bearing, as for instance the wheel shown is rotated, the pendulum will of its weight swing around the shaft 21, rotating the same. The worm shaft will drive the worm wheel slowly, the speed of the worm wheel depending upon the ratio between the wormand the worm wheel. At each complete revolution of the worm wheel the roller 26 will engage the cam plate 36, and will swing the pawl 33 to cause the pawl to advance the shaft 16. The worm wheel is loose on the portion 17 of the shaft. Were the ratio between the several parts as follows: namely, the ratchet wheel with 24 teeth the worm wheel turning once for every 100 revolutions of the worm shaft, the pawl would be operated once in every 100 revolutions of the worm shaft, to advance the pluner rod 16 one tooth. Therefore, the ratchet wheel makes a complete revolution for every twenty-four complete revolutions of the worm wheel. The plunger rod having forty threads will require forty complete revolutions of the ratchet wheel to drive the plunger from one end to the other of the container. It follows that 96000 revolutions of the container about the crank shaft or the spindle will be necessary to emptythe cons tainer. Were the container revolving about the shaft 250 R. P. M.'it would require six hours and twenty-four minutes to empty the one end connected to the pawl, and the other I clai1n: j 1.
